FIELD OF THE TECHNOLOGY

The present invention relates to a wireless communication field, andmore particularly to a multi-mode base station technique.

BACKGROUND OF THE INVENTION

In recent years, the communication technique, especially the mobilecommunication technique, has been developing rapidly. The firstgeneration mobile communication system to the third generation (3G)mobile communication system have been proposed in succession, so thatthe mobile communication has produced more and more significant effectson the people's daily life and work. Recently, the number of users ofthe mobile communication is continuously increasing, and various typesof mobile services are released accordingly. As for this continuouslyexpanded market, each large mobile operator in the world strives toattract and maintain the users of the mobile communication by quicklyproviding new mode services, thereby enhancing the competitiveness inthe market.

Two solutions to realizing the new mode service exist in the prior art.

In the first solution, a new mode base station is added based on theoriginal mode, so as to form an overlay communication network, whichprovides different mobile services for the users. The problem of thissolution is that a large investment and operation cost is required inorder to establish such an overlay network, for example, a large cost isrequired for purchasing equipment, acquiring a site, establishing thesite, as well as network operation and maintenance.

The second solution is directed to a multi-mode base station type, inwhich one existing mode base station is reconfigured into a base stationof another mode, or another mode is added for the base station of theexisting mode, so that the base station is reconfigured into amulti-mode base station.

Briefly speaking, a multi-mode base station refers to a base stationthat supports more than two wireless air interface modes in one basestation cabinet, for example, the wireless air interface modes of globalsystem for mobile communication (GSM), wideband code division multipleaccess (WCDMA), code division multiple access 2000 (CDMA2000) aresupported at the same time.

During realization, base band boards of different modes are inserted inthe same base band frame of the base station, so as to form a multi-modebase station. As for the realization method, fixed slots are assigned todifferent modes in advance. For example, the first to fourth slots areassigned to the WCDMA mode, and the fifth to eighth slots are assignedto the GSM mode. In different modes, radio frequency circuits betweenthe base band boards and a radio frequency unit are also different. Ifthe modes corresponding to the slots are fixed, the radio frequencycircuits between the boards and the radio frequency unit arerespectively set according to the mode for each slot.

For the multi-mode base station, when a new mode is added, the old modeboard may be disassembled, and the new mode board is assembled into thecorresponding slot, for example, the GSM board is disassembled, and theWCDMA mode board is inserted, so that one mode base station isreconfigured into a base station of another mode. Alternatively, the newmode module is directly inserted into the corresponding slot, forexample, the WCDMA board is added to the base station already having theGSM mode board, so that the base station is reconfigured into amulti-mode base station, as shown in FIG. 1.

On the whole, the advantage of the second solution compared with thefirst solution lies in saving the cost of the sites and cabinets.However, the new and old mode modules do not have a uniform design, sothat the common problems of the two solutions are as follows.

Firstly, it is relatively inconvenient to reconfigure the mode includingadding and deleting the mode. Secondly, the resource is somewhat wasted,and cannot be shared.

SUMMARY OF THE INVENTION

The multi-mode base station includes at least two protocol processingmodules and an interface processing module.

The at least two protocol processing modules are respectively vested inat least two modes, and are adapted to process data and/or signaling ofthe mode according to a protocol corresponding to the mode.

The interface processing module is adapted to distinguish the mode ofthe data and/or the signaling while receiving the data and/or thesignaling, and distribute the data and/or the signaling to the protocolprocessing module corresponding to the mode.

It can be known through comparison that the main difference between thetechnical solution of the embodiments of the present invention and theprior art lies in setting a corresponding protocol processing module andone shared interface processing module for each mode supported by thebase station.

The multi-mode base station sets a corresponding resource managementmodule for each mode, and further sets one shared global resourcemanagement module for all the modes. The global resource managementmodule is adapted to assign an available resource scope to each mode.The resource management module corresponding to each mode is adapted toassign a required resource to the protocol processing module in theavailable resource scope of the mode. Since the resource managementmodule of each mode is under a macro control of the global resourcemanagement module, the global resource management module can adjust theresource scopes among different modes according to the loadingsituations, so that the shared resources are assigned and managed in abetter way, thereby improving a resource utilization rate.

Through the architecture of the embodiments of the present invention,the reconfiguration of the multi-mode base station can be performedconveniently. If it intends to add a new mode, it is only necessary toadd a corresponding protocol processing module and a resource managementmodule, and if it intends to delete a certain mode, it is only necessaryto remove the protocol processing module and the resource managementmodule corresponding to the mode, so that the reconfiguration can beperformed conveniently and quickly. In addition, the dynamicconfiguration may be adopted to ensure that the current service is notaffected during the reconfiguration.

DETAILED DESCRIPTION OF THE EMBODIMENTS

In order to make objectives, technical solutions, and advantages of thepresent invention more comprehensible, a detailed description of thepresent invention is given below by reference to accompanying drawings.

In the embodiment of the present invention, a corresponding protocolprocessing module and one shared interface processing module are set foreach mode supported by a base station. The interface processing modulereceives external data and/or signaling, distinguishes the mode of thereceived data and/or signaling, and transmits the data and/or thesignaling to the protocol processing module corresponding to the mode.Each protocol processing module processes the received data and/orsignaling according to a protocol corresponding to the mode. Thus, themulti-mode base station forms a logical entity while supportingdifferent protocols, thereby transmitting and receiving the data andperforming the management operation in a unified manner, so that theoperation complexity is reduced, the resources are conveniently sharedby each mode, and the reconfiguration of the modes could be implementedeasily.

A multi-mode base station in the present invention refers to a basestation that supports at least two modes, including a GSM mode, a CDMAmode, a worldwide interoperability for microwave access (WiMAX) mode, aWCDMA mode, a time division synchronous code division multiple access(TD-SCDMA) mode, a CDMA2000 mode, a personal handy phone system (PHS)mode, a cluster mode, a long term evolution (LTE) mode, and an airinterface evolution (AIE) mode.

A first embodiment of the present invention is described as follows, inwhich a multi-mode base station and a method for operating a basestation are described. The multi-mode base station includes: at leasttwo protocol processing modules, respectively vested in at least twomodes, and adapted to process data and/or signaling of the modeaccording to a protocol corresponding to the mode; an interfaceprocessing module, adapted to distinguish the mode of the data and/orthe signaling while receiving the data and/or the signaling, anddistribute the data and/or the signaling to the protocol processingmodule corresponding to the mode; resource management modules,separately corresponding to each protocol processing module, and adaptedto assign resources required for processing the data and/or thesignaling to the corresponding protocol processing modules; and a globalresource management module, adapted to assign an available resourcescope to each mode, in which the resource management modulecorresponding to each mode assigns the resources to the protocolprocessing module within the available resource scope of the mode.

For example, a multi-mode base station shown in FIG. 2 supports fourmodes, that is, the GSM, the WCDMA, the CDMA2000, and the WiMAX, so thatthe base station includes: protocol processing modules respectivelyvested in the four modes, that is, a GSM mode protocol processingmodule, a WCDMA mode protocol processing module, a CDMA2000 modeprotocol processing module, and a WiMAX mode protocol processing module;corresponding resource management modules, that is, a GSM mode resourcemanagement module, a WCDMA mode resource management module, a CDMA2000mode resource management module, and a WiMAX mode resource managementmodule; and an interface processing module and a global resourcemanagement module shared by each mode. Each mode shares the interfaceprocessing module and the global resource management module, so that thebase station receives the external data or signaling of each mode, andflexibly allocates the internal resources. Thus, the multi-mode basestation forms a logical entity, thereby performing the managementoperation in a unified manner, so that the operation complexity isreduced, and the resources are conveniently shared by each mode.

During realization, the resource management module corresponding to eachmode and the global resource management module may be deployed on onephysical entity, or even combined into one realizing module. Theresource management module corresponding to each mode and thecorresponding protocol processing module may be deployed on one physicalentity.

In this embodiment, as for IP data and/or signaling, the interfaceprocessing module distinguishes the mode of the data and/or thesignaling according to an address and/or a port number of the dataand/or the signaling. As for an asynchronous transfer mode (ATM), theinterface processing module distinguishes the mode of the data and/orthe signaling according to the address and/or a permanent virtual linenumber of the data and/or the signaling.

The dynamic operation process among each module in the multi-mode basestation is described through an operation flow of the multi-mode basestation, as shown in FIG. 3.

In Step 301, the base station receives data and signaling from anexternal transmission link. The interface processing moduledistinguishes the mode of the received data or signaling, anddistributes the data or the signaling to the protocol processing modulecorresponding to the mode for being processed. The interface processingmodule may distinguish the mode of the data or the signaling throughdifferent addresses+port numbers. Taking IP data and signaling forexample, the mode of the IP data and signaling may be distinguishedaccording to an IP address and a transfer control protocol (TCP)/userdatagram protocol (UDP) port number. The interface processing moduleneeds to manage and maintain a mapping relation table about“Mode-Address-Port”, as shown in Table 1. According to the table, theinterface processing module can uniquely determine the mode of thereceived data or signaling. The table may be adjusted according to thepractical requirements, in which one wireless mode can correspond to aplurality of IP addresses and a plurality of port numbers, but the sameIP address or port number can only correspond to one wireless mode.

TABLE 1 Wireless Mode TCP Port UDP Port Protocol IP Address NumberNumber WCDMA 10.121.37.46 2000 2001, 2500-3500 WCDMA 10.121.37.47 /3000-4000 CDMA2000 10.121.37.46 2100 2101, 3500-4000 WiMax 10.121.37.482000 2001, 3000-4000 . . . . . . . . . . . .

As known from Table 1 that, when the IP address of the received data orsignaling is 10.121.37.46, the TCP port number is 2000, the UDP portnumber is 2001 or any port number between 2500 and 3500, the interfaceprocessing module determines that the data or the signaling is the dataor the signaling of the WCDMA mode, and distributes the data or thesignaling to the WCDMA mode protocol processing module.

Next, in Step 302, after receiving the data or the signaling, theprotocol processing module corresponding to the mode applies to theresource management module of the mode for resources. As for the aboveexample, after receiving the data or the signaling, the WCDMA modeprotocol processing module applies to the WCDMA mode resource managementmodule for resources required for processing the data or the signaling.

Next, in Step 303, the corresponding resource management moduledynamically assigns resources in the available resource scope of themode according to processing requirements. In the above example, theWCDMA mode resource management module dynamically assigns the requiredresources to the WCDMA mode protocol processing module in the availableresource scope of the WCDMA mode.

The available resource scope of each mode is assigned by the globalresource management module in advance, and then the global resourcemanagement module notifies the resource management module correspondingto each mode of an assignment result, so that the resource managementmodule corresponding to each mode freely assigns resources in theavailable resource scope of the mode. Because the resource managementmodule of each mode is under a macro control of the global resourcemanagement module, the global resource management module may adjustresource scopes among different modes according to the loadingsituations, so that the shared resources may be assigned and managed ina better way, thereby improving a resource utilization rate.

The assigned resource scopes include universal resources supporting eachmode of the base station and resources only supporting a single mode,and the resources may be divided as follows.

According to different functions of the resources, the internalresources of the base station may be divided into transmission resourcessuch as transmission bearings and port numbers, base band resources suchas modulators, demodulators, encoders and decoders, and radio frequencyresources such as transceivers and power amplifiers, and the like.

According to the resource assigning occasions, the internal resources ofthe base station may be divided into static resources and dynamicresources. The static resources refer to resources assigned duringinitialization, which are usually not released during the operationprocess of the base station. The dynamic resources refer to resourcesdynamically assigned and released according to the user services duringthe operation process of the base station.

According to the wireless modes supported by the resources, the internalresources of the base station may be divided into dedicated resourcesand universal resources. The dedicated resources refer to resources onlysupporting a certain specific wireless mode, and the universal resourcesrefer to resources supporting a plurality of wireless modes.

The global resource management module assigns the available resourcescope of each mode according to the characteristics of each type ofresources. For example, the resources only supporting a single mode areassigned to the available resource scope of the mode, and cannot beshared by the other modes. The resource management module correspondingto each mode dynamically or statically assigns the resources in theavailable scope thereof according to the characteristics of each type ofresources. In this step, the WCDMA mode resource management moduleassigns dynamic resources.

Next, in Step 304, the WCDMA mode protocol processing module uses theresources assigned by the resource management module thereof to processthe received data or signaling according to a protocol corresponding tothe WCDMA mode.

After the WCDMA protocol processing module finishes processing the dataor the signaling, the flow proceeds to Step 305, in which the WCDMA moderesource management module releases the assigned relevant dynamicresources.

The basic modules of the multi-mode base station have been describedabove. In addition, the multi-mode base station further includes areconfiguration module. When the multi-mode base station supports a newmode, the reconfiguration module is adapted to configure a protocolprocessing module and a resource management module corresponding to thenew mode in the multi-mode base station, add information required fordistinguishing the new mode in the interface processing module, andinstruct the global resource management module to assign an availableresource scope to the new mode. When the multi-mode base station doesnot support a certain existing mode any more, the reconfiguration moduledeletes the protocol processing module and the resource managementmodule corresponding to the mode, deletes the information fordistinguishing the mode from the interface processing module, andinstructs the global resource management module to release the availableresource scope assigned to the mode. When a new mode is supported or anold mode is invalidated, it is only necessary to add or delete thecorresponding protocol processing module and resource management module,so that the reconfiguration becomes quite convenient.

When the multi-mode base station does not support the existing mode andreleases the available resource scope assigned to the mode, thereconfiguration module reassigns the released available resource scopeto the other modes currently used by the base station according to apreset policy or a user instruction, thereby further improving theutilization rate of the public resources.

Through the reconfiguration, the base station is configured from onemode to another mode, or from a state of supporting one mode to a stateof supporting multiple modes, as shown in FIG. 4. The reconfigurationmodule configures or deletes the corresponding protocol processingmodule and resource management module in a static or dynamic manner. Thedifference there-between is that, after statically configuring ordeleting the corresponding protocol processing module and resourcemanagement module, the reconfiguration module needs to reset the basestation, so as to support the new mode or invalidate the old mode;whereas after dynamically configuring or deleting the correspondingprotocol processing module and resource management module, thereconfiguration module does not need to reset the base station tosupport the new mode or invalidate the old mode. Thus, the dynamicconfiguration is adopted to further ensure that the current services arenot affected during the reconfiguration.

There are many manners for realizing the dynamic configuration, and anexample of realizing the dynamic configuration by dynamicallyloading/unloading upgrade software is cited below. When a new mode issupported by using the upgrade software, the services of the existingmodes are not interrupted during the upgrading process. The resources ofthe new mode can share the resources of the existing modes, or can besupported by a newly-added hardware module.

In this example, software packages of different modes need to be issuedrespectively (each mode corresponds to one software package), and may beloaded and run independently. During realization, the base stationdownloads protocol processing software of a designated mode from a fileserver according to a reconfiguration command from the user, anddynamically loads and runs the corresponding protocol processingsoftware through a dynamic loading interface of an operating system, soas to realize the reconfiguration, as shown in FIG. 5.

The dynamic support on the newly added modes is realized flexibly byadopting the dynamic loading and unloading techniques, so that theservices of the current modes are prevented from being affected. Thedynamic loading and unloading techniques need the support of theoperating system.

The vxWorks is set as an example below to demonstrate pseudo-codes ofoperations of dynamically loading and deleting a mode.

... Parse reconfiguration_command( ) ; RetrieveProtocol_Processing_software; fdX = open (“/devX/objFile”, O_RDONLY);loadModule (fdX, LOAD_ALL_SYMBOLS); close (fdX);

The multi-mode base station is reconfigured in the software manner, sothat the operations of assembling and disassembling the physical modulesare reduced. For example, when it intends to delete an existing mode, itis only necessary to unload the application software for the protocolprocessing module of the mode, instead of disassembling thecorresponding board, so that the reconfiguration is realizedconveniently and quickly, without requiring any labor work carried outby the management personnel.

In a second embodiment of the present invention, a wirelesscommunication network is described, which includes at least onemulti-mode base station described in the first embodiment. Acorresponding protocol processing module, a corresponding resourcemanagement module, a shared interface processing module, and a sharedglobal resource management module are set for each mode supported by themulti-mode base station. The interface processing module receivesexternal data and/or signaling, distinguishes a mode of the receiveddata and/or signaling, and transmits the data and/or the signaling tothe protocol processing module corresponding to the mode. Each protocolprocessing module processes the received data and/or signaling accordingto a protocol corresponding to the mode. Thus, the multi-mode basestation forms a logical entity while supporting different protocols,thereby transmitting and receiving the data and performing themanagement operation in a unified manner, so that the operationcomplexity is reduced, and the resources are conveniently shared by eachmode. Since the resource management module of each mode is under themacro control of the global resource management module, the globalresource management module may adjust the resource scopes among thedifferent modes according to the loading situations, so that the sharedresources may be assigned and managed in a better way, thereby improvingthe resource utilization rate.

Distinctly, those skilled in the art should appreciate that each moduleor each step of the present invention may be realized by universalcomputing devices, and may be integrated on a single computing device,or distributed in a network formed by a plurality of computing devices.Optionally, each module or each step of the present invention may berealized by program codes executable by the computing device, so thateach module or each step may be stored in a storage device for beingperformed by the computing device. Alternatively, each module or eachstep of the present invention may be respectively fabricated into eachintegrated circuit module, or a plurality of modules or steps among themodules or steps of the present invention is fabricated into a singleintegrated circuit module for realization.
